Summary of the invention
According to above technical matters, the lifting screw that the utility model provides a kind of stable rising or falling speed easy to use fast, comprises base for supporting, housing, lifting bolt, retainingf key, brake ratchet, large bevel gear, bevel pinion, bearing, nut, bottom thread, jacking sleeve, load-bearing jacking, is characterized in that: also comprise movable base, movable pulley, lift cylinder, hold-down arm, top screw thread, handle, the lower end of described movable base is provided with movable pulley, described base for supporting is provided with hold-down arm, base for supporting is arranged on the upper end of movable base by described hold-down arm by lift cylinder, the upper end of described base for supporting is provided with housing, described large bevel gear is arranged on the place of bottom centre of housing by bearing, described bevel pinion and large bevel gear Vertical Meshing are installed, described brake ratchet is arranged on the gear wheel shaft of bevel pinion, the bottom of described lifting bolt is fixedly fixed on the inner side of large bevel gear by retainingf key, the outside of described lifting bolt is provided with nut, described jacking sleeve is corresponding with on nut is provided with bottom thread, the lower end of described jacking sleeve is screwed onto the outside of nut by bottom thread, described jacking sleeve is corresponding with on housing is provided with top screw thread, the upper end of described jacking sleeve is screwed onto the inner side of housing by top screw thread, the upper end of described jacking sleeve is provided with load-bearing jacking, described load-bearing jacking is provided with handle.
Described movable base offers can for the opening of base for supporting lifting.
The hand of rotation of described lifting bolt and jacking sleeve is contrary.
The pitch of described top screw thread is greater than the pitch of bottom thread.
The beneficial effects of the utility model are: the utility model improves in original lifting screw, be arranged on the upper end of movable base by lift cylinder by base for supporting, both movement of the present utility model had been facilitated, by lift cylinder, base for supporting and earth surface can be fixed again, make of the present utility model fixing more stable; Additionally use upper and lower section of screw thread and carry out transmission, not only increase rising or falling speed, reduce the power that driving handle needs, more laborsaving when the utility model is used, more convenient, also disperse stressed by top screw thread, lower thread, substantially reduce the infringement that the excessive double thread of load-bearing connects, thus extend service life of the present utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
According to Fig. 1, the utility model is further described:
As Fig. 1, base for supporting-1, housing-2, lifting bolt-3, retainingf key-4, brake ratchet-5, large bevel gear-6, bevel pinion-7, bearing-8, nut-9, bottom thread-10, jacking sleeve-11, load-bearing jacking-12, movable base-13, movable pulley-14, lift cylinder-15, hold-down arm-16, top screw thread-17, handle-18.
Embodiment 1
The utility model comprises base for supporting 1, housing 2, lifting bolt 3, retainingf key 4, brake ratchet 5, large bevel gear 6, bevel pinion 7, bearing 8, nut 9, bottom thread 10, jacking sleeve 11, load-bearing jacking 12, movable base 13, movable pulley 14, lift cylinder 15, hold-down arm 16, top screw thread 17, handle 18, base for supporting 1 is provided with hold-down arm 16, be provided with bottom thread 10 jacking sleeve 11 is corresponding with on nut 9, be provided with top screw thread 17 jacking sleeve 11 is corresponding with on housing 2, first large bevel gear 6 is arranged on the center of base for supporting 1 during installation by bearing 8, the bottom of lifting bolt 3 is fixedly fixed on the inner side of large bevel gear 6 by retainingf key 4, then bevel pinion 7 and large bevel gear 6 Vertical Meshing are installed, brake ratchet 5 is arranged on the gear wheel shaft of bevel pinion 7, again nut 9 is fixedly mounted on the outside of lifting bolt 3, the lower end of jacking sleeve 11 is screwed onto the outside of nut 9 by bottom thread 10, housing 2 is arranged on the upper end of base for supporting 1, the upper end of jacking sleeve 11 is made to be screwed onto the inner side of housing 2 by top screw thread 17, then load-bearing jacking 12 is arranged on the upper end of jacking sleeve 11, handle 18 is arranged on load-bearing jacking 12, finally movable pulley 14 is arranged on the lower end of movable base 13, base for supporting 1 is arranged on by hold-down arm 16 upper end of movable base 13 by lift cylinder 15.
